Customer_id:136 AND state.name:("new" OR "open" OR "pending reminder" OR "pending close")

hello,
when I am in a ticket and then click on customers one level up, I see the ticket count on the right side.
When I click on it, the search in the view does not give any result although there are three tickets open.

Does anyone have any idea what it could be… have the latest update from zammad

thx
Tony
